标题: 关于审稿人询问自旋污染的问题 [打印本页] 作者Author: LZLLLL 时间: 2020-11-19 16:23 标题: 关于审稿人询问自旋污染的问题 审稿人问:The authors considered different spin states for each metal center: have they checked the stability of the wavefunction and spin contamination in each structure?
我是用B3LYP/6-311G*,对过渡金属用的SDD基组优化的结构,而且结构都用stable=opt查看过波函数稳定性,都是稳定的,但是自旋污染要怎么查看呢?我翻了之前关于自旋污染的帖子,三重态的结构最终的输出 S**2 before annihilation 2.6160, after 2.0203, 在2左右应该是可以忽略自旋污染的吧?那么该如何回复审稿人呢? 作者Author: sobereva 时间: 2020-11-20 04:01
你就把<S**2>告诉审稿人,说偏离理想值非常小,自旋污染可以忽略作者Author: LZLLLL 时间: 2020-11-20 13:11
好的,谢谢Sob老师作者Author: csu-77 时间: 2023-11-28 21:11
借楼请教sob老师几个问题,先行感谢,近期论文收到了一条这样的审稿意见如下——“It is unclear why the authors chose the B3LYP functional, which is known for its limitations in describing transition metal complexes. This choice should be justified through a comparison with one or two other functionals or by citing relevant literature reports. Additionally, since the systems in this study have open-shell characteristics, the discussion should address spin contamination in the context of these systems.”
具体请教问题如下:
1)学生在做过渡金属(钴和锰)萃取的计算过程中,采用B3LYP-D3BJ/6-311G*进行的几何优化和振动分析,采用M062x-D3/ma-TZVP进行的单点能计算(计算体系中包含阴离子结构),因为之前看过sob老师发布的一条评论,大致是:过渡金属萃取时,配合物中只有一个金属原子,用B3LYP也是可以接受的,所以针对上述审稿意见前半段的回复,可以直接引用一些过渡金属萃取过程计算用B3LYP泛函的文章,而不做不同泛函的对比嘛?
2)至于“Additionally, since the systems in this study have open-shell characteristics, the discussion should address spin contamination in the context of these systems.”,这个不知如何解答?还望得到老师的指导,万分感谢作者Author: zjxitcc 时间: 2023-12-2 20:57 本帖最后由 zjxitcc 于 2023-12-2 20:59 编辑
